Currently there are no plans to create and distribute native Linux packages.
Oxygen is not a native Linux application (it's Java-based), so there are no real benefits for us from using native packages. We also prefer to bundle a specific version and build of Java runtime that only Oxygen uses, rather than let Oxygen depend on a system installed Java runtime of random version.
There's also the aspect that we prefer to create and test a single Linux package that works on all distributions, rather than having separate Linux packages for multiple distributions. Currently the single .sh installer package satisfies our requirements.
